Several billion seasons of development and suddenly the writers introduce this "humanity" group. I get that it's for dramatic purposes but their characterization is wildly inconsistent, their plotline is all over the fucking place, and half the time it's totally unclear if they're supposed to be the protagonists or the villains.

Don't get me wrong, there's potential there, but they could also be the reason the whole thing comes to a crashing, unsatisfying ending. And if that happens, I'm going to be pissed.

Of course, I've been bitter ever since they wrote the thylacine out of the story in favor of humanity, so maybe I'm biased here.

So let me get this straight... These American guys acquire this super-weapon that ultimately ended a massive war in a previous season... but this 'super-weapon' is never used again in all the later wars they get into?

It was a pretty clever transition how WWII sets up the whole US vs. Soviet plot line that runs for several episodes. But then it's like the Soviet Union left to make a movie or something, the writers just killed it off overnight with no foreshadowing.
